Abstract
Abstract A data correlation system used in a process line for elongated product includes a pulse generating tachometer driven at a speed proportional to product speed before entering a product accumulator, and a second tachometer driven at a speed proportional to product speed after the accumulator. A bidirectional counter which is operated by the pulses is connected to an N-level matrix decoder to provide an output corresponding to the variable product length in the accumulator. One of a series of logic AND gates is enabled by the decoder to insert into a corresponding shift register element a data signal from a sensor appropriate for the type of data desired. The shift register, operated by pulses from the second tachometer is connected to a data accumulator and logger which receives the data signal from the shift register as the product region associated with the data signal passes a reference point in the process line.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
165 words
A data correlation system for production data accumulated from an elongated product moving through a process line and acquired at a fixed location in said process line, said process line having a bidirectional counter continuously measuring the units of length of product in a variable length storage unit located in said process line beyond said fixed location comprising sensor means at said fixed location in said process line for producing an electrical data output signal related to production data associated with a portion of said product, means connected to said bidirectional counter for producing a plurality of storage signals each representing a specific number of units of elongated product length in said variable length storage unit, a shift register connected to said means for producing storage signals and having a first plurality of stages equal in number to the number of said storage signals, and means connected to said means for producing storage signals for inserting said electrical data output signals into said shift register.
Claim 2
Dependent Claim
165 words
A data correlation system for production data accumulated from an elongated product moving through a process line and acquired at a fixed location in said process line, said process line having a bidirectional counter continuously measuring the units of length of product in a variable length storage unit located in said process line beyond said fixed location comprising sensor means at said fixed location in said process line for producing an electrical data output signal related to production data associated with a portion of said product, means connected to said bidirectional counter for producing a plurality of storage signals each representing a specific number of units of elongated product length in said variable length storage unit, a shift register connected to said means for producing storage signals and having a first plurality of stages equal in number to the number of said storage signals, and means connected to said means for producing storage signals for inserting said electrical data output signals into said shift register.
Claim 3
Dependent Claim
58 words
Apparatus according to claim 1 including a second fixed location in said process line located beyond said variable storage unit, means for generating an electrical pulse for each unit of elongated product length passing said second fixed location, and means responsive to said pulse generating means for sequentially shifting said electrical data output signals in said shift register.
Claim 4
Dependent Claim
104 words
Apparatus according to claim 2 including a second plurality of stages in said shift register connected sequentially to said first plurality of stages and equal in number to the number of units of elongated product length equivalent to the distance from said fixed location to said variable length storage unit and from said storage unit to said second fixed location, and means responsive to said pulse generating means for sequentially shifting said electrical data output signals in said second plurality of stages in said shift register and reading out said electrical data output signals from said second plurality of stages from said shift register.
Claim 5
Dependent Claim
26 words
Apparatus according to claim 3 including a data accumulator and logger connected to the output of said shift register and responsive to said pulse generating means.
